Uhh. Yeah that was abused. If you had called your dealer when the damage started they absolutely would have covered it. We have many regencies out there that are way over 10 years with no problems. Mine has been a full time burner for 10 years and has no issues.My 2 cents - Stay away from the Regency if you are planning on a lot of burning. After 10 years of heavy burning, the baffles and tubes are totally disintegrated as the pic will show. Regency says I "did not maintain" so the 'lifetime warranty' was denied. Regardless of the warranty, the stove will not take the abuse of being the main heat source.
Did you not notice anything going wrong before you burnt the tubes off?
